Local Group Policy Editor is a Windows utility that lets you manage parts of Windows, enforce certain policies, and automate repetitive tasks.

  2. In the left pane, choose Administrative Templates under Computer Configuration.

  8. Click Apply > OK to save the changes.

4. Clear the SecurityHealth Folder

Whenever you upgrade Windows, your computer creates a SecurityHealth folder, which contains the security settings of the previous Windows version. But if the content of the SecurityHealth folder gets corrupted due to any reason, you become prone to different issues, including one in the discussion.

You will have to clear the content of the SecurityHealth folder to solve the issue. Here’s how:

  1. Press the Win + E hotkeys to open the File Explorer.
  2. Open the C drive, and navigate to Windows > System32.
  3. In the System32 folder, locate and open the SecurityHealth folder.

  4. Select everything inside using Ctrl + A hotkeys and then press Shift + Delete to delete them permanently.

Restart your computer and check if the problem persists.

5. Reset the Windows Security App

Windows 11 comes with a reset option that you can use to get rid of most of the built-in app issues. The reset option restores the application to its default settings.

You can reset the Windows Security app by following the below instructions:

  1. Open the Settings menu by pressing the Win + I hotkeys.
  2. Choose Apps from the left panel.
  3. Select the Installed apps option in the following window.

To repair the Windows Security app, navigate to Settings > Apps > Installed apps. Here, click the three dots next to Windows Security and select Advanced options from the menu that pops up.

Next, scroll down and click the Repair button to initiate the process. Once the Windows Security app is repaired, you’ll see a checkmark next to the Repair option.

6. Download the Latest Windows Update

The problem can also occur if you are using an outdated Windows version. The solution, in this case, is to download the latest Windows update.

  1. Open the Settings menu and choose Windows Update from the left panel.
  2. Click the Check for updates button.

Windows will now look for and download any available updates. You might have to restart your computer to successfully install the downloaded update.

7. Reset Your PC

Are you still facing the issue? If yes, then you are left with no option other than to try the Reset Your PC setting. It resets your computer and brings it to its initial stage, which is far better than reinstalling the whole Windows.

To get started, follow the below steps:

  1. In the Settings menu, navigate to System > Recovery.
  2. In the Recovery window, click the Reset PC button next to Reset this PC.
